which motor?

[de-pro]

Longer can and the rotor. UL-1 draws less amps than the Leopard so you can use cheaper ESC's with the UL-1 motor

so why not use the better motor if its the same size other then a little longer? if the motor is a more powerful one wouldnt you be able to run less throttle and therefore less hea and longer life? its that way in rc cars maybe its not the same but just thinking.

I'm new to boating but certainly not new to brushless setups. Longer can motors produce more torque but for the price of drawing more amps. You can use the UL-1 motor with any esc around 60-80 amps range but you cant use the 74mm can in anything less than 120 amps. Also UL-1 motor is rated for 4 or 5 cells lipo when Leopard can handle 6. So if you have the money then buy the Leopard and a 120+ amps esc.
One thing you have to keep in mind is the size and the application of the boat. Too much power is not a good thing if the boat cant handle it. Just a waste of money.

running lower throttles does not draw less amps or use less power, if anything it is more abusive on the ESC
